It starts on the A2214 on the edge of Peckham Rye common and heads south along one of the roads called Peckham Rye, with housing to the right and the common to the left. The road TOTSOs right at a slight bend, when it meets the B238 which continues along the common.

Now called Barry Road, the B219 continues southwestwards along a dead-straight road through East Dulwich. A church spire is visible in the distance along most of the road (the building is now used as a hostel). The B219 bends right at the former church and ends shortly afterwards at a set of traffic lights on the A2216 opposite Dulwich Library.
